APPARATUS FOR USE IN PRODUCING COPIES OF WRITINGS, DRAWINGS, AND THE LIKE.

SPECIFICATION forming part of Letters Patent No. 389,452, dated September 11, 1888.

Application filed February 2, 1888. Serial No. 262,703. (No model.) Patented in England April 5, 1887, No, 5,007.

To all whom it may concern.-

Be it known that l, EUGENIO DE Zuooaro, a subject of the Queen of Great Britain, and a resident of London, England, have invented new and useful Improvements in Apparatus for use in Producing Copies of \Vritings, Drawings, and the Like, (for which I have obtained a patent in Great Britain, No. 5,067, bearing date April 5, 1887,) of which the following is a specification, reference being had to the accompanying drawings.

My invention is designed to improve the construction and increase the efficiency of ap paratus of the kind or class described in the specification of former Letters Patent granted to me and dated February 4, A. D. 1879, No. 211,877that is to say, apparatus for holding stencils during the operation of producing copies or facsimiles of writings, drawings, or the like by the process set forth in the said former specification. Such apparatus as hitherto constructed comprises a frame having connected thereto by means of hingejoints two metal bars, which fit into grooves in the said frame for the purpose of stretching and holding the stencil thereon. The said frame is, moreover, provided with hooks for seenring the said bars in their grooves. A board or slab is arranged between the said metal bars and serves for supporting beneath the stencil the sheet of paper on which the copy or facsimile is to be produced. Ihis board or slab is connected at one of its edges by means of hinge-joints to the aforesaid frame, and is supported at its opposite edge by a lever pivoted to the said frame and provided with ahandle, whereby it may be turned upon or about its pivot. By turning the said lever in one direction the said board may be lowered or inclined to permit the introduction of the paper between the same and the stencil, and by turning the said lever in the reverse direction the said board may be raised to bring the paper into contact with the under surface of the stencil.

According to one part ofiny present invention I adapt apparatus of the kind or class above mentioned for holding or containing the indiarubber scraper, the bottle of ink, and other articles required in the process of producing the copies or facsimiles. For this purpose I make the said apparatus in the shape of a box, the stretching-frame forming the sides and the hinged board or slab serving as the lid of the said box. By this means I am enabled to dispense with the box which has heretofore been supplied for containing the frame or stencilholding apparatus and the scraper and other articles required for use therewith. I thus reduce the cost of the entire apparatus and make the same very compact.

According to another part of my present invention I make the front portion of the box movable and connect the same by means of hinge-joints to the bottom of the box, and I provide the said front portion with one or more curved projections or cams on its inner side. The front edge of the aforesaid board or slab rests upon these projections or cams, which are so formed that by turning the said front portion upon its hinges in one or the other direction the said board may be raised or lowered for the purposes above specified. By constructing the apparatus in this manner I am enabled to dispense with the aforesaid lever.

In the accompanying drawings, Figure 1 is a plan; Fig. 2, a front elevation; and Fig. 3, a transverse section on the line am, Fig. 1. Fig. 4. is a front elevation illustrating a modification of my said invention; and Fig. 5,a transverse section on line w m, Fig. 4.

Like letters indicate corresponding parts throughout the drawings.

A is the box or stretching-frame, the front part, A, of which is pivoted at a.

B is the board or slab for supporting the stencil. This board or slab is connected by hinge-joints at b to the box A and forms the lid of the said box.

0 is the projection or cam on the inner side of the front part, A, of the box A.

D D are the bars for stretching and holding the stencil.

E E are the hooks for securing the said bars in their grooves.

The front part, A, of the box A is provided with hooks 0, adapted to engage with eyes (I, fixed in the board or lid B, which extends over the part A, as shown in Fig. 3. Other suitable means may, however, be provided for fastening the lid of the said box when closed.

In using my improved apparatus the bars D are turned back and astencil formed as described in my said former specification is placed upon the box or frame A,'and is stretched and secured thereon by means of the said bars. The front part, A, of the box is then turned down and the board or lid B thus lowered or inclined, as shown in dotted lines in Fig. 3, and a sheet of paper is placed upon the said board or lid. The part A is then turned upward, thereby raising the said board or lid by means of the projection or earn 0 and bringing the paper into contact with the under surface of the stencil. A copy or facsimile may then be produced upon the said sheet of paper in the manner described in my said former specification, after which the front part, A, of the box is again turned down to permit the removal of the said sheet and the insertion of a fresh sheet of paper.

Stops A are sometimes provided on the box A to support thelid B when inclined as above described.

To provide foreffectually preventing lateral displacement of the bars D. I sometimes em ploy slotted or notched metal pieces 0, which are secured to the ends of the box so that they extend upward above the same,and so that the bars D, when in their grooves, will fit into the slots or notches in the said metal pieces 0, as shown in Fig. 2. In other cases I make the front portion of the box with extensions at each end thereof, which extensions project above the top of the box and are formed with vertical slots or grooves, and I make the bars D of such length that their free ends will fit into the said slots or grooves when the said bars are in the grooves in the box A.

The hinges of the lid B are so made that the said lid may be opened to permit the placing asas of the scraper, the bottle of ink, and other articles in the box.

The aparatus is, in some instances, constructed,as shown in Figs. 4 and 5,with a framefied, and the lever described in thesaid former specification being dispensed with.

By my present improvements the operation of producing the copies or fac-similes is greatly facilitated and the entire apparatus can be made more compact and produced at a lower cost than heretofore.

What I claim isr 1. An apparatus for the production of facsimiles of writings, drawings, or the like,consisting of the box-frame A, the stencil-supporting lid 13, hinged at one edge to the frame and adapted to swing downward and upward, a front board, A.,and swinging stretching-bars D, hinged at one end for holding the stencil, substantially as described.

2. The combination of the boxframe A, the stencil-supporting lid 13, hinged at one edge to the frame and adapted to swing down into the box, a front board, A, hinged at its lower edge to the frame and having a projection, C, on its inside to raise the lid, and means, substantially such as described, for holding the stencil above the hinged lid.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

EUG. DE ZUCOATO.
